The Sub 2000’s unique folding carbine design limits optic placement and demands lightweight, low-profile, and compact optics that can handle its recoil and folding mechanism. After testing numerous scopes and red dots, I’ve narrowed down the top performers that balance optical clarity, compactness, and adaptability for the Sub 2000’s tactical versatility.
Whether you’re using your Sub 2000 for range fun, home defense, or truck gun duty, these scopes provide excellent accuracy and durability without interfering with the gun’s folding feature.
Top 5 Best Scope for Kel Tec Sub 2000 Gen 2 of 2025
Here’s my curated list of the best scopes for the Kel Tec Sub 2000 Gen 2. All are compact, rugged, and proven to work perfectly with this folding PCC platform:
1. Primary Arms SLX 1-6x24mm SFP Illuminated ACSS Gen III
Short Description: The Primary Arms SLX 1-6x24mm SFP with the ACSS Gen III reticle is one of the best low-power variable optics (LPVOs) for the Sub 2000. It combines close-quarters speed with the ability to reach out accurately to 100 yards or more. Compact, rugged, and feature-rich, it’s ideal for the pistol-caliber carbine platform.
Product Specs:
Pros:
Cons:
Glass Clarity & Reticle: The glass offers surprisingly good edge-to-edge clarity. The ACSS Gen III reticle allows for rapid target holds, moving from close to mid-range seamlessly. I found the reticle illumination adequate for both daylight and dusk shooting.
Eye Relief & Eye Box: Eye relief is comfortable around 3.3–3.5 inches. The eye box is forgiving at 1x, allowing quick engagement when shooting off-hand.
Durability: Tested through multiple range sessions and some rough handling in a range bag, the SLX held zero perfectly. It’s shockproof, waterproof, and nitrogen purged.
Elevation & Windage Knobs: The 0.5 MOA clicks are crisp and tactile. Turrets are capped for field reliability.
Magnification & Parallax: Smooth zoom from 1x to 6x. Parallax is factory-set for 100 yards—perfect for 9mm PCC distances.
Mounting & Accessories: I recommend using a QD cantilever mount like the American Defense AD-RECON-S for easy removal when folding.
My Personal Experience: Mounted on my Sub 2000 using a Midwest Industries rotating mount, I could still fold the rifle completely by rotating the scope aside. Zeroing took only 8 shots at 50 yards. After over 600 rounds, zero retention was flawless.
